Abstract

A nickel base alloy for making a gas-turbine blade (see Group XXII) has the following percentage composition by weight: Cr 5-30; Co 0-30; Mo 5-30; W 0-20; Ti 0.5-7.0; Al 2-17; B 0.003-0.3; Zr 0.001-1.0; C 0.01-0.5; Ca 0-0.1; Mn 0-0.4; Si 0-0.4; Fe 0-1.0; Be 0-0.5; Ta 0-5; Nb 0-5 Hf 0-10; rare earths 0-0.2; S 0-0.005; P 0-0.008; V 0-3; N2 0-0.2; Mg 0-0.15; combined O2 0-0.2; Cu 0-0.5; Pb 0-0.005. The combined Ti and Al content is at least 6.5% and the balance of the alloy is nickel and impurities there being at least 35% Ni if cobalt is present or at least 45% Ni without cobalt.
